Designing
Behavior Change
with IoT.
I create technologies that seamlessly
connect the digital and physical worlds, drawing on
Human-Computer Interaction (HCI) and Human-Food Interaction (HFI).
Using IoT-driven olfactory devices, soft-robotic interfaces, multimodal conversational agents, and large-scale behavioral data, my work explores how subtle sensory and social cues can shape human behavior. My goal is to design calm, intuitive systems that enrich everyday life—guiding people toward healthier habits, meaningful eating experiences, and smarter decision-making without disrupting their natural rhythms.
Daiki Mayumi
I received Doctor of Engineering from the Nara Institute of Science and Technology (NAIST) and a Doctor of Natural Science (Dr. rer. nat.) from Ulm University (Germany) through a double degree program in 2026. I am currently a research scientist at NTT, Inc., Human Informatics Laboratories, where I work on human-computer interaction (HCI). My research focuses on behavior change through information technology.
